Twiztid is an American hip hop duo from Warren, Michigan. The group is composed of Jamie Spaniolo and Paul Methric, who perform under the respective personas of Jamie Madrox and Monoxide Child. Twiztid performs a style of hardcore hip hop known as horrorcore, and have released eight studio albums, six EPs extended play and seven compilations.

Prior to Twiztid, Jamie Spaniolo and Paul Methric were members of the hip hop trio House of Krazees, under the names Mr. Bones and Hektic, along with the third member, the R.O.C. The group released five albums before disbanding in 1997. After the split, Methric and Spaniolo sent a demo tape to Insane Clown Posse member Joseph Bruce. The demo contained the tracks "2nd Hand Smoke," "Diemuthafuckadie," and "How Does It Feel?" Bruce was extremely impressed, invited Methric and Spaniolo to perform on 'The House of Horrors Tour', and signed them to Psychopathic Records. Before the tour kicked off, Bruce, Methric and Spaniolo decided on a name that they felt would fit the duo—"Twiztid". Twiztid's 1997 debut album, Mostasteless, was originally released independently by Psychopathic. When Insane Clown Posse signed with Island Records, they helped get a deal for Twiztid as well. After a show in Indianapolis, Twiztid's tour bus stopped at a Waffle House in Greenfield, Indiana. Spaniolo and Joseph Bruce became involved in an altercation with a customer causing a fight to break out between the lone customer and all of the bands' members. Months later on June 4, 1998, Twiztid were charged with battery.

Cypress Hill is an American hip hop group from South Gate, California. Cypress Hill was the first Cuban-American/Latino hip hop group to have platinum and multi-platinum albums, selling over 18 million albums worldwide. It is one of the most well-known groups in West Coast rap and was critically acclaimed for their first two groundbreaking albums.

Senen Reyes (also known as Sen Dog) and Ulpiano Sergio Reyes (also known as Mellow Man Ace) are brothers who initially lived in South Gate, California. In 1971, their family had immigrated to the United States, settling in the Los Angeles neighborhood of South Gate. In 1988, the two brothers teamed up with Lawrence Muggerud (also known as DJ Muggs) and Louis Freese (also known as B-Real) to form a hip-hop group named DVX (Devastating Vocal Excellence). The band soon lost Mellow Man Ace to a solo career, and changed their name to Cypress Hill, after a street in South Gate.

After recording a demo in 1989, Cypress Hill signed a record deal with the major label, Columbia Records. Their self-titled first album was released in August 1991. The lead single was the double A-side "The Phuncky Feel One"/"How I Could Just Kill a Man" which received heavy airplay on urban and college radio. The other two singles released from the album were "Hand on the Pump" and "Latin Lingo", the latter of which combined English and Spanish lyrics. The success of these singles led to the album selling two million copies in the US alone. The group made their first appearance at Lollapalooza on the side stage in 1992.
